I had this leather-trimmed steering wheel on our old R Reg Escort but have no idea what car it was originally from.
Someone suggested an Escort Cosworth but I don't think so. I suspect it's more likely to have been a lower-spec Escort, though I'll be happy to be wrong!
The part number on it is 94AB3600AC, the diameter is 36cm, and the leather trim around the two upper spokes is perforated.
